Abstract

An additive manufacturing apparatus that makes it unnecessary to use a heater power supply, and makes it possible to attempt to reduce the cost, by effectively using an electron beam, and a modification method therefor are provided.In an additive manufacturing apparatus includes: a conductive stage 2 arranged in a vacuum chamber 1; a conductive base plate 3 arranged on a top side of the stage 2; a metal-material supply device 5 that supplies a metal material 4 onto a top side of the base plate 3; an electron beam gun 7 that irradiates, with an electron beam 6, the metal material 4 supplied by the metal-material supply device 5, and melts and solidifies the metal material 4; a grounding circuit 8 that grounds the stage 2 and the base plate 3; and a controller 9 that controls the metal-material supply device 5 and the electron beam gun 7. The additive manufacturing apparatus includes a resistance heating element 11 that is arranged between the stage 2 and the base plate 3, and generates heat by a current produced by electron-beam emission from the electron beam gun 7.
